There are sounds that wake you up out of a deep sleep, only to be dismissed as you fall back to sleep. And then there are sounds that rivet you, make you sit bolt upright.

That was the type of sound that woke us while we were deep in the backcountry of Yellowstone National Park. Sunrise hadn’t yet come, yet we were wide awake, listening to one of the most mesmerizing sounds you can encounter in the wilds: The melodious rising and falling howl of a wolf.

It was late summer in 2008 when two friends and I were lucky enough to catch that howling. Had it been 20 years earlier, there would have been an audible hole in the park sky because there were no wolves in Yellowstone in 1988.

It was an effort launched early in the 1990s that returned the predators to the park in January 12, 1995 – 30 years ago – when 14 wolves trapped in Canada were brought into Yellowstone to kick off an audacious effort to see healthy wolf packs loping through the park.

How have they done? To find out, our guest today is Eric Clewis, the Northern Rockies senior representative for Defenders of Wildlife.

We’re five days into 2025, and already there’s a lot of news concerning national parks and the National Park Service. Traveler Editor-in-Chief Kurt Repanshek is joined today by Contributing Editor Kim O’Connell to discuss the Traveler’s 4th Annual Threatened and Endangered Park Series and other recent park-related news.

Many of us like to take a walk in our favorite national park, whether it’s a short stroll down one of the boardwalks at Yellowstone National Park, the hike to the top of Old Rag at Shenandoah National Park, or up the Mist Trail at Yosemite National Park, we like to get out and experience parks up close.

As you might imagine, there are walks in the National Park System, and then there are walks. Kevin Fedarko and his photographic sidekick Pete McBride took one of those “other” hikes in Grand Canyon National Park. And it didn’t initially go as planned. While Fedarko raised some serious blisters on his feet that required duct tape to protect, McBride almost needed a medical evacuation from the backcountry.

Still, the hike - or rather hikes - generated a compelling book from Fedarko titled, appropriately enough, “A Walk in the Park: The True Story of a Spectacular Misadventure in the Grand Canyon”.
